Allegro Cozumel

Fire at Cozumel Hotel   August 15, 2022

A diver’s favorite, the Allegro Cozumel, has closed after a fire in its palapas spread to the main complex. A few of the 575 guests were injured. Read more about this in the upcoming September Undercurrent issue, including their problems with fire alarms, water pressure, and more.

It’s Crazy During Florida’s Two-Day Lobster Mini Season   August 15, 2022

Four people died, at least two while snorkeling, one perhaps struck by a boat during the two-day event. Officials found scores of people with undersized lobster -- one group of four had 27 undersized lobster -- and people hauling more lobster than permitted.

Been Around Rude Divers? Let Us Hear From You  August 15, 2022

Have you ever been on a trip where rude divers affected your diving? Where, perhaps, they refused to follow direction so the captain could not go to certain dive sites? Or where they refused to make certain dives, so the captain changed the itinerary? Or they insisted on certain dives? Or they were always late, or maybe overstayed their bottom time affecting the next dive? Let us know how other divers have affected any trip you've taken. Email with your story, not forgetting to tell your town and state.

Understand What Your Computer Tells You  August 15, 2022

Most divers try to stick to no-deco-stop times and ascend to the shallows as their displayed NDL time displayed diminishes. However, occasionally you may overstay your welcome at depth, and your computer switches displays to show a stop depth and time or minimum ascent time. Be aware of this so that you don’t, at best, send your computer into SOS mode or, at worst, send yourself for emergency recompression. If you don’t fully grasp this, read the instructions that came with your computer.

Baby Turtle Dines on Plastic  August 15, 2022

A baby green sea turtle found lying on its back in a rock pool near Sydney, Australia, had eaten so much plastic that it took six days for it to be excreted, according to Taronga zoo’s wildlife hospital. A veterinary nurse told The Guardian that once it started to defecate, no feces came out, just pure plastic. This little guy is just one of millions, if not billions, of examples of how the eight million tons of plastic that pour into our oceans destroy our wildlife.

At Least Someone is Doing Something About Plastic  August 15, 2022

Volunteer divers removed 43 tons -- the weight of a commercial airliner -- of plastic and rope ghost nets from a Hawaiian Reef during the first week of August. Maro Reef is part of the Papahånaumokuåkea Marine National Monument more than 800 miles from Honolulu and lies in a shallow lagoon less than 10 feet deep. PM Debris Project volunteers recovered the ghost nets in early August.

Komodo Only for the Well-Heeled?   August 15, 2022

Latest news is that the Indonesian authorities have bowed to pressure from local businesses and have put off raising the tourist entrance fee for the Komodo National Park until next January.

Ten Caught Trafficking Corals   August 15, 2022

Let this be a warning if you’re tempted to bring back a little bit of coral as a souvenir. In April, a federal grand jury indicted 10 people on misdemeanor charges for smuggling protected marine corals from the Philippines for retail sale. The penalties range from five to twenty years in jail and a $250,000 fine. Coral could become the most expensive thing on your mantlepiece.

Goliath Grouper May Get a Break   August 15, 2022

Earlier this year, the Florida Wildlife Commission opened limited goliath grouper fishing over objections from the diving community and many others. The opponents continued to press for no fishing at spawning sites between July 15 and October 15, when spawning is most active. Noted conservationist Lad Akins, and members of Palm Beach Diving Association, made the case at the July FWC rule-making meeting, and now the FWC is proposing rules to prohibit catch and release fishing of goliath grouper at three of the 11 known spawning aggregation sites. Hopefully, they’ll act in September.

Another Dive Resort Bites the Dust   August 15, 2022

The Bohio Dive Resort on Grand Turk is no more, Irene Beck of Fly and Sea Dive Adventures tells us. It looks like dive travel wholesalers in North America and divers who booked directly will lose their funds and vacations. The website says “it is closed for refurbishment.” Stanbrook Prudhoe on Grand Turk are the liquidators.
